This is related to Homebrew/homebrew-core#216372. The Homebrew formulae is not pinned to a specfic Go version and has recently updated to go1.24.

The specific problem is likely in an upstream package (e.g. github.com/onflow/crypto) and will be resolved when this repo updates to go1.24 and makes the required changes.

For this reason, this bug only affects Homebrew builds, but manual installs remain functional.

I suggest you to try fixing this, to not depend on Go 1.23, which will be supported only until August 2025 when Go 1.25 is scheduled for release and support for Go 1.23 will be dropped.
See https://go.dev/wiki/Go-Release-Cycle
